SAMUEL B. EASLEY AND ORUS J. EASLEY, OF DEFIANCE, OHIO.

SQUARE.

To all whom 'it may concern:

Be it knownthat we, SAMUEL B. EAsLEY and ORUs J. EASLEY, citizens of theUnited.

States, residing at Deance, in the county of Defiance and State of Ohio,have invented new and useful mprovements in Squares, of which thefollowing is a specification.

This invention relates. to squares, and more particularly to attachmentstherefor, and has for an object to provide an attachment which may bereadily applied and adjustably mounted upon the -arms of an ordinarycarpenters square and which may be used to nd various angles and to markthe cuts of rafters or the like.

A further object of this invention is to provide an attachment which maybe accurately adjusted whereby the scale marks may assume their correctposition with respect to the material to be out.

@ther objects and advantages will be apparent as the nature of theinvention is better disclosed, and it will be understood that changesmay be made within the scope of the claim without departing from thespirit of the invention.

In the drawing, forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews,-Figure 1 is a plan view of a square showing the applica-tion ofthe invention thereto and in a position upon a rafter, Fig. 2 is a planview of one of the arms of the square showing the attachments insection, Fig. 3 is a perspective view of the gage, Fig. 4 is an endview.

Referring now more particularly to the drawing, there is shown a square5 of ordinary construction provided with the usual arms 6 and 7respectively, each of which being provided with a scale 8. Upon the arm6, there is mounted the present attachment which will be hereinafterdescribed or called the gage and consists of parallel side walls 9 and10, and end walls 1l and 12 respectively. The wall l2 is preferably ofwedge shape and provided with a rearwardly eX- tending enlarged portion13 and a pointed or reduced outer portion 14C. The construction is suchthat a slot 15 is formed in the gage to receive the arm 6. The forwardedges of the walls 9 and 10 adjacent to the pointed end 14 of the wall12 are flattened or extend substantially at right angles as Specicationof Letters Patent.

Application led August 7, 1908.

shown at 16 to said wall 12 and are adapted to lie in parallel relationto the scale marks upon the arm 6. The wall 11 of the gage is somewhatthick, and has formed therein a threaded passage 17 to receive anadjusting screw 18 for engagement with one edge of the arm 6 to securelyhold the gage at its proper point of adjustment. By constructing thegage with the wall 12 of wedge form as described, it will be seen thatthe gage may be moved until the end 14 thereof is brought to registerwith the desired mark upon the arm and from this construction will liein a position with respectto the material which should be marked wherebythe said desired mark will lie close to said material to be cut to thusprovide an accurate device as will be appreciated.

The arm 7 is provided with a gage 19 which is identical in constructionto the previously described gage, but which is somewhat smaller, asshown. Upon reference to Fig. l, it will be seen that a rafter A, isshown and that the gage upon the arm 6 is set at the six-inch mark, andthe gage upon the arm 7 is set at the seven-inch mark to thus make a sixby seven inch cut in the rafter.

The parallel walls 9 and 10 are beveled from a point adjacent to one endof the wall l2 inwardly to a point adjacent to the wall 11, and theopposite edges of said walls are provided with concavities of arcuateform as clearly indicated at 1()ZL in the drawing. By providing thebeveled portions just described, and by providing the concavities 10a itwill be readily understood that the scale marks or graduated portions ofthe square or measuring instrument with which the attachment is usedwill be readily visible by the carpenter or workman.

We claim:

The combination with a square having graduated arms, of a gage slidablymounted on each arm and comprising spaced parallel walls straddling thearm, end walls connecting the said spaced walls, the upper end wallbeing of wedge form with its outer face beveled uniformly from one endto an edge at its angle of intersection with its opposite end, said edgebeing adapted to register with the graduations on the arm, and a setscrew carried by the lower end wall adapted to be engaged with theinstrument to hold the gage in its adjusted position, said parall ielWailsuof said. gage having their edges at gglhd with tvhich the en'dsiotthe Wedge i@ one side provided With piane upper and shaped top Weil arein register. flower faces and intermediate arcuate con- In testimonywhereof We a-HX our signa-1 cavities, and having their edges at theother tures in presence of two Witnesses.
